You're not the only one I'm very similar if not maybe the same? When someone dies I don't cry and others tend to think I'm some sort of heartless monster. But instead I cry because I feel bad for myself or for no important reason which similar towards my anger and self harm. I don't see a therapist also, I think it's just the way I am. We're all humans not angels that all have the same personality. Everyone's different. Some just take it to heart more than others.

Don't feel bad it could be just be random mood swings... I get that a lot.
